1 # Configure fragment invoked in the post-target section for subdirs
2 # wanting multilib support.
4 # It is advisable to support a few --enable/--disable options to let the
5 # user select which libraries s/he really wants.
7 # Subdirectories wishing to use multilib should put the following lines
8 # in the "post-target" section of configure.in.
10 # if [ "${srcdir}" = "." ] ; then
11 # if [ "${with_target_subdir}" != "." ] ; then

17 # . ${srcdir}/../config-ml.in
21 # Things are complicated because 6 separate cases must be handled:
22 # 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
24 # srcdir=. is special. It must handle make programs that don't handle VPATH.
25 # To implement this, a symlink tree is built for each library and for each
28 # The build tree is layed out as
37 # The nice feature about this arrangement is that inter-library references
38 # in the build tree work without having to care where you are. Note that
39 # inter-library references also work in the source tree because symlink trees
40 # are built when srcdir=.
42 # Unfortunately, trying to access the libraries in the build tree requires
43 # the user to manually choose which library to use as GCC won't be able to
44 # find the right one. This is viewed as the lesser of two evils.
46 # Configure variables:
47 # ${with_target_subdir} = "." for native, or ${target_alias} for cross.

50 # tree. It exists to handle the case of configuring in the source tree:
51 # ${srcdir} is not constant.
52 # ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
55 # MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
56 # (FIXME: note that this is different than ${with_multisrctop}. Check out.).
57 # MULTIBUILDTOP = number of multilib levels in build tree
58 # MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)
59 # (only defined in each library's main Makefile).

64 # newlib. It is up to each target to turn on multilib support for the other
65 # libraries as desired.
